` Application filed February 26, 1883, (No model.)

county of Rock and State ofv Visconsin, have invented certain new and useful Improvements in CookingStoves; and we do hereby declare the following -to be a full, clear, and'exact de-y scription of the invention, such as will enable others skilled in the art to which it pertains tov make and use the'same. i y i This invention relates to cooking-stoves for burning coal or wood, its object being to secure a more thorough utilization, distribution, and'.

management `of the heat than has been practi cable heretofore in stoves of this class.

The invention consists, mainly, in a cooking stove having an oven communicating with an annular space entirely surrounding the iirepot, and also preferably the ash-pit, except such portion of the latter as is necessary to be i accessible for` the removal of ashes, and it con` sists, besides, in certain novelconstructions and combinations of hues and 'dampers, and in a removable heat-distributer, and the combination of the same with the oven and rire-` pot, all as will be hereinafter particularly de-A walls around the fire-pot' and ash-pit being' broken away. Fig. 2 is a top view of the stove withlthe boiler removed. tal `section on the line x a", Fig. l, Fig. 4, a similar view on line`33. Fig. 5 is a vertical section on the line y y, Fig. 2. Fig; 6 is a detached perspective view of the removable heat-dis tributer. Fig. 7 is a top view of a range embodying our invention. Y

The letter A indicates the oven, which is inclosed by its top plate, a, bottom plate, c, rear wall, a2, the front wall, a, the partial side walls, a?, and the doorsV a, The top plate, a, has its forwardportion depressed and prb` vided with an opening, through which is sus- I pended theffire-pot B, which is entirely sur-` rounded by the oven, as will be seen.)`

`The letter C designates the ash-pit, arranged l below the re-pot and mainly within the oven,

from the open space of which it-is partitioned Fig. 3 isa horizon` off by a curved wall, c, and a horizontal partition, c', through which the lower portion of 'Y the lire-pot extends. Between` the top plate, I), and base-plate D ofthe stove are ues E and E', which connect witha vertical iiue, FF,

which is between the back wall, c', ofthe oven Y tial partition g, a complete partition, which causesthe products of combustion from the fire-pot to flow, entirely downward through the diving-lues F F to theflue E, which passes under the oven and thence to the verti cal' iiue E2. These swinging dampers may be turned down either forward or rearward. When turned forward, they will close the top openings of the diving-fines, and,while opening the draft through the top flue, will alsopre- `vent any heat from passing through the bot= tom line by way of the diving-dues. Experience has shown that heat will reach the flue under the oven through the diving-dues even though the top draft-rlue be open. When the dampers are turned rearward,they simply open the top draft-flue and permitheatat the same time to pass down through the diving-dues,

though in limited quantity.

` Immediately to the rear of the lower ends of the stove-top plate is arranged transversely at about the middle of said plate, and behind Tof the diving-hues a swinging damper, h, is g arranged across the flue under the oven, `and and partly at the ends of this thimble is formed i an opening, q, over which is to be arranged the boiler Q., said boiler beingA located infront of a heating-oven, O, which is located upon the rear portion of the stove-top plate.

extremities. To the rear of these wing-walls g are arranged oblique delecting-plates z' i, the outer ends of which extend nearly to the side walls of the stove, and the inner ends of which are separated by a narrow passage at the top of the vertical iiue Ei. The object of these wing-walls and deflecting-plates is to secure a thorough distribution of the hot air and products of combustion under the boiler Q, and heating-oven O. The boiler Q is 'removable 5 but its lid Q is hinged to the heating-oven, so that it will always be in place when wanted. Y

In the rear wall of the oven are apertures t, governed Vby a sliding damper-plate, T, Aprovided with apertures in the usual manner, and by operating this damper-plate it will be seen that a draft of hot air may be caused to flow through the oven from the vicinity of the fire-pot, when desired, and thorough ventilation of the oven be thus effected.

' The letter S indicates a heat-distributer,

located Within the oven, directly in the rear of the fire-pot. This heat-distributer consists of a vertical center plate, s, having its lower edge, in the present instance, insertedin a slot formed to receive it in the bottom plate of the oven, and to the vertical-edges of this "center plate are .hinged the wing-plates s,

which may be folded back behind the center plate or at any desired angle, or may be turned to vclose the spaces between the edges of the center plate and the diving-fines. It will be readily understood that by closing one of these passages and opening the other the heat may be thrown mainly to one side of the oven; or, by opening both passages slightly, the heat may be deflected from the center and to the sides of the oven, while by opening` both passages even distribution of heat will be 'caused throughout the oven. This heatdistributer maybe supported inany convenient manner, and may be suspended fr om the top or side walls of the oven.

In the side walls of the stove, on each side of the fire-pot, are set perforatedplates o', through which air iows to the fire-pot, and is heated thereby to form the hot-air currents, whichv iiow through and heat the oven from the interior.

V is the door of the ash-pit, to which access is had through the front wall of the stove, and the bottom of which is formed by the front portion of the bottom-plate, 'D'.

In the top view,`=Fig.'4r 7, is illustrated a simple modification ofthe arrangement of the stove pipe thimble and deflecting plates, adapting the same for a range. l In'this-modificationthe pipe-thimble p is arranged at'one side ofthe plate D, so as to come immediately behind one ofthe diving-lues,and .one of the deflecting-plates, as shown at i', is prolonged to touch the side wall of the stove-thimble.

4This prolongation of the deilecting-plates prevents the upward draft from the vertical flue Qassam.

prefer to use a single wing-wall, g2, extending from the middle of the partial partition. In a range, which is usually somewhat longer than a stove, the pot and boiler holes may be arranged over the space to the rear of the partial partition g and the dampers, as well as in the front thereof.

Having now fully described our invention, we wish it to be understood that we do not limit ourselves to the .precise details and the construction and arrangement of devices shown in our drawings, but may vary the same in any suitable manner for the better carrying out of our invention without departing from the essential principle thereof.
